Gardner says Showell and 68-year-old Gerald Lee of Camden arrived at the house shortly before 2 p.m.

Investigators say Showell and Lee were looking for a burgundy GMC pickup, which they did not realize was parked behind the house. But in front they found a similar red truck with a tag number nearly identical to the one on the truck behind the home.

The sheriff's department says Alton Shelley appeared on or near the front porch with a handgun.

Showell, driving the wrecker, was hit at least once and was dead by the time deputies arrived. Lee was not hurt.

Shelley is charged with murder and aggravated assault. At last report he was being held at the Sumter-Lee Detention Center.

A man next to the shooting scene who identified himself as Shelley's son-in-law called the shooting a "tragedy", but declined further comment.
